Step 1:
There are a variety of reasons you may need to reboot a Lenovo laptop. These can include the installation of a new program, the dreaded blue screen of death or to free up memory that has been hijacked by a program that is now closed. There are three ways to reboot and all are simple to accomplish.

Click on your start menu button on your screen. Click on "Shut Down" or "Turn Off Computer." Click on the drop down box if you are running a version of Windows before XP (such as 2000 or 98). Select the "Restart" option and then click "OK." On XP or later versions, click on "Restart." The laptop will then reboot. Press and hold down the "Alt," "Ctrl" and "Shift" keys simultaneously. This will bring up the Task Manager. Pressing and holding the same keys again will force the computer to shut down. Press the power button to reboot the computer. This feature should be used when the mouse has stopped working and you cannot access the start button. Hold the power button in the "Off" position for approximately 5 seconds. This will force the machine to shut down. Press or slide the button again to reboot the laptop. Use this process when you get the "blue screen of death" or the computer is not responding to either the mouse or the keyboard.

First - re-seat the hard disk and reboot the computer. If the computer does not boot up then reboot and go into the BIOS configuration to see if the BIOS detects the hard drive. If it doesn't detect the hard drive then it could be faulty.
Then the hard drive needs to be replaced in the computer/laptop, Windows installed and the computer or laptop's device drivers plus your programs etc. to get a functioning computer/laptop again.

You don't need disks to reboot. Just click "Turn off computer" under the start menu, and then click "Reboot". If that doesn't work, hold down the power button. After ten seconds or so, your computer will shut off, and you can restart it again simply by pressing the power button again.

Hello

By know you should of fixed the problem .
1. keep the inside cabinet clean.
2.If the unit keeps shutting down by itself after a certain time and it is not dirty inside the cabinet .Also all the intact screens are clean . Check your Personlization settings By right clicking on your screen . then right click Screensaver and then power settings . Then check to make sure all the settings are turned off unless you want the computer to shut down after a certain amount of time

OverheatingWhen the CPU overheats then it will shut down (i.e. thermaloverload) and won't boot up again until it has cooled down. If this is theproblem is not fixed then the CPU will eventually fail.
A faulty fan causes the problem or the fan and heat sink assembly are cloggedwith dust.
Check the CPU fan to see if it spins freely, if not replace the fan.
If the fan and heat sink is clogged with dust the remove the dust and make surethe vents are clear and dust free. Use a small brush and can of compressed airto do this.

Reboot essentially means restarting the computer. This is two types
1. Warm Reboot: where you go to start on windows task bar and choose shut down but when prompted choose restart. This way computer shuts down momentarily and restarts!
2. Cold Reboot: By this means you choose to shut down and again when prompted choose shut down! This makes computer off completely until restart by pressing power button.
Booting is computer Lingo for above procedures!

Check you power settings. It is possible that it is set to shut down at 50% battery power.

If it is overheating, that too will cause a shutdown. What is happening at the time of shut down? Are the vents on the laptop being blocked in any way?

Hi,

To restore your Dell computer to it's original factory settings, here's how:

To use PC Restore:

1. Turn on the computer.
   
   

During the boot process, a blue bar with www.dell.com appears at the top of the screen.

1. Immediately upon seeing the blue bar, press .
   
   

If you do not press in time, let the computer finish starting, and then restart the computer again.
NOTICE: If you do not want to proceed with PC Restore, click Reboot in the following step.

1. On the next screen that appears, click Restore.
   
   
2. On the next screen, click Confirm.
   
   

The restore process takes approximately 6-10 minutes to complete.

1. When prompted, click Finish to reboot the computer.
   
   

NOTE: Do not manually shut down the computer. Click Finish and let the computer completely reboot.

1. When prompted, click Yes.
   
   

The computer restarts. Because the computer is restored to its original operating state, the screens that appear, such as the End User License Agreement, are the same ones that appeared the first time the computer was turned on.

1. Click Next.
   
   

The System Restore screen appears and the computer restarts.
After the computer restarts, click OK.

Thanks and have a good one.

The most common shut down problem is that the system will reboot rather than shutting down. In most cases, the reboot is triggered because Windows XP is designed to reboot after a critical failure. To stop windows from rebooting in case of a failure, you need to take the following steps:
Right click on My Computer, Select Properties, Click on advance tab, Click on Settings under Startup and Recovery, Uncheck the option Automatically Restart under System failure, Click Ok twice and try to shutdown the pc. If it shows any error code then let me know
